Moscow Subway Bombings

From the BBC:

March 29 2010: Two suicide bombers blew themselves up at
Lubyanka station and Park Kultury station, killing 35
people.
The attacks, in the morning rush hour, killed at least 38
people and injured more than 60, officials say.
No group has said it carried out the attacks, but security
services have blamed rebels from the North Caucasus - which includes
Chechnya and Ingushetia.

President Dmitry Medvedev laid a wreath at the scene of one
of the attacks, labelling the plotters "beasts".
He said: "We will find and destroy them all."

The first explosion tore through a carriage of a train at
central Lubyankastation at 0756 (0356 GMT) as it stood
waiting for commuters to board.
The station lies beneath the headquarters of the Federal
Security Service (FSB).
The second explosion, six stops away at Park Kultury, came
at 0838 (0438 GMT). It hit the back of the train as people were getting on
board.

The GCP event was set for 07:30 to 11:30, which includes
almost half an hour before the first explosion and some
three hours following the last. The result is Chisquare
14534.512 on 14000 df, for p=0.214 and Z=0.794.

It is important to keep in mind that we have only a tiny
statistical
effect, so that it is always hard to distinguish signal from
noise. This means that every "success" might be largely
driven by chance, and every "null" might include a real
signal overwhelmed by noise. In the long run, a real effect
can
be identified only by patiently accumulating replications of
similar analyses.
